CSM RE8040-HUE

Summary

Product identification

The RE8040-HUE is a normal grade reverse osmosis (RO) element designed for ultra pure water applications, featuring high TOC rejection.

General Features:

• Membrane type: Thin-Film Composite
• Membrane material: Polyamide (PA)
• Element configuration: Spiral-Wound, FRP Wrapping

Specifications

• Permeate flow rate: 9,000 GPD (34.1 m³/day)
• Nominal salt rejection: 99.5%
• Minimum salt rejection: 99.4%
• Effective membrane area: 400 ft² (37.2 m²)
• IPA rejection: 96.0% (after 2 hours of operation)

Performance is based on data taken after 30 minutes of operation at the following test conditions:

• 2,000 mg/L NaCl solution at 225 psig (1.5 MPa) applied pressure
• 15% recovery
• 77 °F (25 °C)
• pH 6.5–7.0

IPA rejection test conditions: 1,000 mg/L IPA solution at 225 psig (1.5 MPa) applied pressure, 15% recovery, 77 °F (25 °C), pH 6.5–7.0.

Permeate flow rate for each element may vary but will be no more than 10% below the value shown.

Mechanical / hydraulic

Dimensions:

• A = 40.0 inch (1,016 mm)
• B = 8.0 inch (203 mm)
• C = 1.12 inch (28 mm)

All RE8040 elements fit nominal 8.0 inch (203 mm) I.D. pressure vessels. Each membrane element comes with one brine seal, one interconnector (coupler), and two o-rings.

Operating limits

• Max. Pressure Drop / Element: 15 psi (0.1 MPa)
• Max. Pressure Drop / 240” Vessel: 60 psi (0.41 MPa)
• Max. Operating Pressure: 600 psi (4.14 MPa)
• Max. Feed Flow Rate: 66 gpm (15.0 m³/hr)
• Min. Concentrate Flow Rate: 16 gpm (3.6 m³/hr)
• Max. Operating Temperature: 113 °F (45 °C)
• Operating pH Range: 3.0–10.0
• CIP pH Range: 2.0–11.0
• Max. Turbidity: 1.0 NTU
• Max. SDI (15 min): 5.0
• Max. Chlorine Concentration: < 0.1 mg/L

Feed water

Design Guidelines for Various Water Sources (Flux):

• Wastewater Conventional (SDI < 5): 8–12 gfd
• Wastewater Pretreated by UF/MF (SDI < 3): 10–14 gfd
• Seawater, Open Intake (SDI < 5): 7–10 gfd
• Seawater, Beach Well (SDI < 3): 8–12 gfd
• Surface Water (SDI < 5): 12–16 gfd
• Surface Water (SDI < 3): 13–17 gfd
• Well water (SDI < 3): 13–17 gfd
• RO permeate (SDI < 1): 21–30 gfd

Saturation Limits (Using Antiscalants):

• Langlier Saturation Index (LSI): <+1.5
• Stiff and Davis Saturation Index (SDSI): <+0.5
• CaSO₄: 230% saturation
• SrSO₄: 800% saturation
• BaSO₄: 6,000% saturation
• SiO₂: 100% saturation

The above saturation limits are typically accepted by proprietary antiscalant manufacturers. Users are responsible for ensuring proper chemical(s) and concentration are dosed ahead of the membrane system to prevent scale formation.

Handling and Storage Notes

Elements are vacuum sealed in a polyethylene bag containing 1.0% SBS (sodium bisulfite) solution and individually packaged in a cardboard box. Elements must be kept dry at room temperature (7–32°C; 40–95°F) and should not be stored in direct sunlight. If the polyethylene bag is damaged, a new preservative solution (sodium bisulfite) must be added and air-tight sealed. Permeate from the first hour of operation should be discarded to flush out the preservative solution. Elements should be immersed in a preservative solution (e.g., 1% by weight sodium bisulfite or sodium metabisulfite) during storage, shipping, and system shutdowns. Keep elements moist at all times after initial wetting. Avoid excessive pressure and flow spikes. Only use chemicals compatible with the membrane elements and components. Permeate pressure must always be equal or less than the feed/concentrate pressure to prevent damage.
